MOSQUITO-NET FRAME.

SPECIFICATION forming part of Letters Patent No. 515,123, dated February 20, 1894.

Application filed May 12, 1893. Serial No. 473,902- (No model.) i

To wZZ whom, it may concern.-

Be it known that I, ALBERT O. LOTTMAN, of Houston, in the county of Harris and State of Texas, have invented a new and Improved Mosquito-Net Frame, of which the following is a full, clear, and exact description.

Myinvention relates to an improvement in mosquito net frames, and especially to an improvement upon the frame shown and described in the Letters Patent granted to myself December 9, 1890, No. 442,486.

Afurther object of the invention is to construct a mosquito net frame in such a manner that the frame may be utilized to support a tester, if desired, and when a tester is used wherein themosquito netting may be carried outward over the bed, or rearward in direction of the headboard without in the least interfering with the tester, and whereby also the frame may be used without a tester if desired.

A further object of the invention is to construct a frame capable of being expeditiously and conveniently set up for use, which frame will comprise but few parts, the parts acting to brace each other, and further to construct the frame in such manner that it may be applied to a bedstead without injuring or marring it in the slightest degree.

Theinvention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claim.

Reference is to be had to the accompanying drawings forming a part of this specification,

in which similar figures and letters of refer-V ence indicate corresponding parts in both vlews.

Figure 1 is a perspective view of the mosquito net frame, illustrating it as applied to the bedstead; and Fig. 2 is a detail perspective view of one of the side brackets of the frame.

In carrying out the invention two uprights 10 and 11, are employed,which uprights are preferably made round in cross section, but may have any other desired cross sectional shape. The uprights are adapted to be attached to the back of the head board 11 of a bedstead, the attachment being made in any suitable or approved manner. Ordinarily, however, two eyes 12, are used in connection stepped in the lower ones, asshown in dotted lines in Fig. 1.

In addition to the uprights 10 the mosquito net frame comprises two side bracket bars A, a rear fixed bar 13 and a front movable bar 0. The front and rear bars B and C, are preferably made of Wood or equivalent material, while the side bracket bars A, are made of metal, each being in one piece. Thus it will be observed that but few parts comprise the frame. Each upright 10, is usually provided with a shoulder 13 near its upper end, which is ordinarily produced by reducing in diameter the upper extremity of each upright, as shown in Fig. 1, and a predetermined distance below the shoulders 13 of the uprights apertures or recesses 14, are produced in their front or forward faces.

The side brackets are of peculiar construction, and as heretofore stated are preferably made of metal. One of the brackets is illustrated in detail in Fig. 2. The brackets are essentially triangular in general contour and are made ordinarily from one piece of bar iron or steel and comprise therefore an upper member 15 and a lower member 16. The upper member is ordinarily straight while the lower member closely approaches the forward or outer end of the upper member at one extremity and departs or diverges some distance from the upper member at its opposite extremity.

At the forward or contracted end of each side bracket A a depression or loop 17, is formed, the depression or loop being made in the lower member; while at the inner end of the upper member the metal is bent upon itself to form an eye 18, and after the eye is formed the metal is carried at a right angle to the upper member inward, producing thereby an extension or arm 19, as shown in both of the figures.

In placing the parts of the mosquito net frame together, after the uprights 10 have been put in position the eyes 18 of the side brackets are carried over the reduced upper extremities of the uprights to an engagement with the shoulders 13, as shown in Fig. 1, the extensions or arms 19, extending inward between the two uprights; and the arms or extensions 19 of the side brackets are introduced into the ends of the rear bar B, the ends of the said bar being bored or otherwise formed to receive the said arms or extensions.

Prior to placing the side brackets in connectlon with the standards 10, the front bar 0, 1s located upon the brackets. This front bar is provided at each end with an eye 20, and preferably the lower members of the side brackets A, are made to pass through the said eyes, thus enabling the front bar to be slid upon the lower member 16 of the side brackets from one end to the other; and after the upper members 15 of the side brackets have been made to engage with the standards, the inner or rear ends of the lower members of the said brackets are introduced into the apertures 14 of the uprights. Thus it will be observed that the brackets are not only attached to the uprights but are also braced thereon; and it will be further observed that when the front bar 0, 1s carried to the front of the brackets the eyes of the said bar will enter the loops or depresslons 17 near the front ends of the brackets, and the bar will be held thereby in its outer position; but it may be raised from the loops or depressions, and slid along the lower members of the brackets until it engages with or is stopped by the uprights 10. I desire it to be distinctly understood that if in practice it is found desirable the front bar may be made to slide upon the upper members of the brackets A instead of upon their lower members. When the front bar is slid upon the lower members of the brackets the upper members thereof, together with the back bar B, may be utilized to support a tester, if such a device is used; but the tester is not absolutely necessary, and if used the front bar 0 may be manipulated without removing the tester from its support.

In practice the mosquito netting is provided with rings which may be made to slide upon the lower members of the'brackets A, and the mosquito netting is likewise attached to the front bar 0. Thus when the front bar is 1n its outer position, as shown in Fig. 1, the netting will fall down over the bed and will be in position for use. When the mosquito netting is not required for use it may be folded close to the head board by simply carrying the front bar 0 rearward to an engagement withthe uprights 10. When a tester is not employed in connection with the frame the mosquito netting may be carried entirely over the frame; in any event the netting is attached to the back bar B, which falls down back of the head board, and the rear strip of netting may be and preferably is attached to the section of netting located over the bed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A mosquito canopy consisting in the vertical posts 10, 11, reduced at their upper ends forming shoulders and provided in their front faces below the shoulders with apertures 14, the side brackets A each formed of a piece of wire bent between its ends to form the upper horizontal member having an eye 18 receiving the said reduced end and terminating in the lateral extensions 19, and a lower inclined member, the extremity of which enters said aperture 14 a depression 17 being formed at the juncture of the said two members, therear cross bar B having longitudinal apertures in its ends receiving the said extensions 19 and the forward cross bar 0 having eyes 20 at its ends resting in the -said depressions 17; the said bar 0 being adapted to he slid along the said lower members, substantially as set forth.

ALBERT G. LOTTMAN.
